Hi, I have an Asterisk Server with a Public IP (No NAT) and I'm trying to register an adapter SIPURA 2000 behind a NAT Linksys Router WRT54G, but It has been impossible. Into the SIPURA Port #1 I have a Termination with MutualPhone and it works perfect. Into the SIPURA Port 2 I have connection to Asterisk Server but I can't reach it. The configuration on both ports is the same. For this reason I'm sure that the problem must be into de SIP.CONF, but I don't know what is the exactly configuration to SIP's behind of NAT. I tried with NAT=YES and QUALIFY=YES but it doesn't work.!!! Thank you for your advices. CARLOS F -------------- next part -------------- An HTML attachment was scrubbed...
